Hepatitis B virus DNA amount <10³ copies/ml is normal, ≥10³ copies/ml is positive, and ≥10⁵ copies/ml requires antiviral treatment. 1. Hepatitis B virus DNA level <10³ copies/ml is negative and is a normal result. 2. DNA level ≥10³ copies/ml is a positive result, which refers to the presence of hepatitis B virus infection in the body, may be patients with chronic hepatitis B, patients with hidden hepatitis and some virus carriers. 3. DNA content ≥10⁵ copies/ml, or ≥10⁴ copies/ml and e antigen negative, suggesting that the virus is actively replicating in the organism, and the infectiousness is high. It is recommended to refer to the specific indicators of the local hospital for judgment, and consult a specialist, comprehensive liver function, liver ultrasound and other pathogenetic findings of a comprehensive assessment of the condition, if necessary, follow the doctor's instructions to take medication.
